for each particular job. NADCA members are truly committed to our industry.

 

The benefits

Choosing a NADCA-member contractor for your next duct-cleaning job positions you for success. Identifying a local duct-cleaning contractor who holds membership with the association to perform the job offers you unique advantages:

  • High standards. When you work with a NADCA-qualified contractor, you can trust that the business places importance on proper
    education and training for its’s of its technicians, and on following industry standards for cleaning, restoration and assessing the HVAC system.
  • Ethical work practices. To become a member of the organization, contractors must agree to adhere to the organization’s Code
    of Ethics, which supports honoring the customer’s time and investment, as well as adhering to best practices for cleaning.
  • Protection. Members must hold liability insurance as a form of protection for consumers should something go wrong on the job.
    You should never hire any type of contractor that doesn’t hold liability insurance .
  • Certification. At least one person employed by the contractor must be trained by the organization and then certified to
    perform the various tasks associated with cleaning ducts in order to become a member. This practice ensures that the right
    information and training gets passed along to other technicians in the company.
  • Comprehensive cleaning. The organization also requires that contractors agree to follow their cleaning and restoration
    practices for the entire HVAC system, not just the ductwork.

High Tech Furnace Filter

Your Air Filter Just Got Smarter

 

Wouldn’t it be great if your air filter could send you a text
when it became clogged and lost its efficiency?

For many of us, changing air filters is an easily forgettable chore.

Who has time to think about something that is hardly noticed on a daily, or even weekly, basis? Typically, central air conditioning and heating system filters are changed randomly or when it “feels” right.

A new air filter monitor removes this guesswork by sending an email or text alert to your smartphone, tablet or desktop computer when the filter becomes clogged so you can enjoy cleaner air, lower electric bills and an efficiently operating HVAC system.

And, it’s not just convenient. Regular filter changes can help save $300 annually.

Just like your automobile’s gas gauge, the CleanAlert FILTERSCAN WiFi shows how much ‘cleaning power’ remains in your home’s air filter. The monitor continuously tracks the condition of your home’s air filter, and the AirFilterSentry™ Notification Service instantly alerts you of an efficiency-robbing clog. This way, you or your HVAC contractor know exactly when your air filter needs to be replaced.

Theres a Raccoon in my ductwork

In our 48 years of duct cleaning, this one will make the hall of fame

Power Vac Toronto received a call from a customer who was complaining about a bad odor coming from the ventilation system.   We regularly received call from clients about bad smells and sometimes we find dead mice, squirrels, snakes  etc but our service tech was not ready for this one

What we found was unbelievable . The smell was unimaginable . The Power Vac service tech persisted and removed the dead animal from the ductwork . We never did find out how the wild animal was able to get into the ventilation system.

Ultraviolet Lighting

Ultraviolet light used in hvac

Ultraviolet Lighting in HVAC units

Ultraviolet lighting in HVAC units has increased substantially over the years with the
sudden interested in maintaining a healthy indoor environment. This article will
introduce you to the basics of Ultraviolet Lighting

Definition of Ultraviolet Lighting

A rainbow is made when light shines through droplets of water and breaks into is various
colors. The light just beyond the violet end of the spectrum is not visible to the naked
eye and is called ultraviolet light, also commonly knows as UV Light

There are three types of UV light
The three types of UV light are A, B and C representing a different section of the UV light spectrum.
Type C known as UVC is the form used for germicidal activity, When UVC is used for germicidal purposes, it is known as UVGI.
UVGI “deactivates” or kills microorganisms, including viruses, bacteria, molds and other fungi by disrupting their DNA.

UVC is used for
       Surface disinfection
       HVAC Air disinfection
      Cooling Coil disinfection
      Water treatment
      Curing plastics and other materials
      Printing
      Chemical Processing
Application in HVAC Systems

UVGI lamps are categorized by the internal pressure of the gas in the lamp. Low pressure
lamps are the most common types of lamps  found in HVAC system.
On hard surfaces like evaporator coils and drain pans the UVGI exposure is constant and the kill rate is up to 99.9%.
Bio aerosols is a more complex activity and affected by different factors such as system install, number of lamps and
lamp placement. Any installation of a UVC lamp in an HVAC system should include a method of visually inspecting it
periodically. Dirty lamps will result in reduced effectiveness. If the lamp becomes dirty, it should be cleaned with a
lint-free cloth and glass cleaner or alcohol. Never clean the lamp while it is turned on.

Hazards of Ultraviolet Lightings

Material decomposition is a concern in HVAC systems.  UVGI can seriously degrade organic materials over time in a HVAC system,
including filters, sealants, gaskets and wiring insulation, resulting in air leaks, fire hazards and loss of system performance.
It is best to shield all organic material components within 5 feet of the UV lamp.

Skin and eyes have to be protected when exposed to UVA or UVB  Ocular damage can occur 6-12 hours after  initial exposure.
skin damage from excess exposure is similar to sunburn.  Proper protection must be used when working with lamps.

Mercury Exposure is also a concern.  UVC lamps contain a small amount of toxic Mercury, so if a bulb breaks ,
care should be taken to reduce exposure to the Mercury.

Best Practises

It is generally agreed that source removal (Duct Cleaning) of contaminants is the single best method for cleaning and
decontaminating the HVAC system.

If Ultra Violets lights are installed in the HVAC system without proper training, UVC lamps can be ineffective and can
create hazards or material decomposition that can  negatively impact the efficiency of the system.

It is recommended that the installers be well educated on the materials from the manufacturer and in the ASHRAE Handbook – HVAC Systems and Equipment Chapter 17: Ultraviolet Lamp Systems
